In this article we discuss the complementarity of laboratory and field data. Experiments offer highly controlled environments that allow precise testing and causal inferences. Survey and field data on the other hand provide information on large and representative samples of people interacting in...

Identifying the impact of local firm concentration on individual firm performance is likely to produce a selection bias related to the positive effects of local concentration if agglomeration economies and natural advantages coincide. We overcome this problem by exploiting exogenous variation...

Geringqualifizierte haben in Deutschland ein weitaus höheres Risiko arbeitslos zu werden als Fachkräfte. Kann ein subventionierter Niedriglohnsektor - wie er derzeit im Bündnis für Arbeit diskutiert wird - zur Lösung ihres Arbeitsplatzproblems beitragen? In welchem Umfang werden...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

We shed new light on the relative importance that schools’ ability to produce high achievers in math has for economic growth. Drawing on data from the International Mathematical Olympiad (IMO), the world championship in mathematics for high school students, we construct a measure for a...

This study presents results of the validation of an ultra-short survey measure of patience included in the German Socio-Economic Panel (SOEP). Survey responses predict intertemporal choice behavior in incentive-compatible decisions in a representative sample of the German adult population.

We experimentally compare standard two-player trust games to three-player trust games, where two trustors compete for one trustee. We argue that a competitive environment could affect how the trustors’ behaviour is perceived by the trustee. If two trustors compete for the favour of a trustee,...

We test whether new firms locate close to incumbent firms of the same industry. Tendencies to coagglomerate may explain the general wisdom that industry location is highly persistent over time. We perform separate analysis for East and West Germany which enables us to study two integrated areas...
